What would the Syracusan see in this present epoch to remind him of himself? Would he see the man of 212 B.C., at all connected with the men of 1843 A.D.? Yes. In Prussia, Austria, France, England, America, in every city of every civilized nation, he would find the lever, the pulley, the mirror, the specific gravimeter, the geometric demonstration; he would trace the influence of his mind in the power-loom, the steam-engine, in the building of the Royal Exchange, in the Great Britain steam-ship; he would find an application of his well-known invention, the subject of a patent, an important auxiliary to navigation. Alexander _was_ a hero; Archimedes _is_ one. Are we guilty of exaggeration in this contrast of the hero of War with him of Science? We think not. It may undoubtedly be argued that Alexander's life was productive of ultimate good, that he did much to open Asia to European civilization; but would that consideration serve to soothe the gloomy Shade? To what does it amount but to the assertion that out of evil cometh good? It was through no aim of his mind that this resulted, nor are mankind indebted to him personally for a collateral effect of his existence. As an instance of men of a more modern era, let us take Napoleon Buonaparte, Emperor of France, and James Watt of Greenock, civil engineer. The former applied the energies of a sagacious and comprehensive intellect to his own political aggrandizement; the latter devoted his more modest talents to the improvement of a mechanical engine. The former was and is, _par excellence_, a hero of history--we should scarcely find in the works of the most voluminous annalists the name of the latter. What has Napoleon done to entitle his name to occupy so prominent a position? He has been the cause, mediate or immediate, of sacrificing the lives of two millions of men.[17] [17] From a rough calculation taken from the returns of those left dead on the fields of battle in which Napoleon commanded, from Montenotte to Waterloo, we make the amount 1,811,500; and if we add those who died subsequently of their wounds in the petty skirmishes, the losses in which are not reported, and in the naval fights, of which, though Napoleon was not present, he was the cause, the number given in the text will be far under the mark. A picture of the fathers, mothers, wives, children, and relatives of these victims, receiving the news of their death, would give a lively idea of the benefits conferred upon the world by Napoleon.
